When xenografts average size measured 250–350 mm3 in volume, mice were randomized into ≥ 4 mice per group and each mouse was injected intravenously via a tail vein with normal saline or three doses (~ 2.5 mg/kg) of cixutumumab, cixutumumab-PEG6-DM1-Low or cixutumumab-PEG6-DM1-High on day 0, 4, and 8. Tumor growth was monitored using a digital caliper and growth curves were established using the tumor volumes. The study was terminated when xenograft reached a volume ≥ 2000 mm3 and this was used to estimate the Kaplan Meier survival curves in the different groups. Individual body weight of mouse (every other day) was recorded during the quarantine and experimental period. At the dose selected, gross examination of organs and body weights of treated mice did not show dose limiting toxicity.
